Point 50,51 is projected upwards in the side that load is acted on respectively.Also, the symmetric position of the two sides in the first contact 30 is dividually matched
It is equipped with the second contact 50,51.It therefore, can be centered on the first contact 30 on load position X1 and by 30 He of the first contact
The contact pressure of second contact 50,51 assigns connecting object component 61.In addition, the first contact 30 is inserted into through hole 52 and is penetrated through
Hole 52 guides, therefore is able to suppress the deformation of lesser first elastic arm 11 of spring constant in the in-plane direction, and also can
Inhibit the deformation of the second elastic arm 12 in the in-plane direction.
In the state that the first contact 30 as shown in Figure 6 and the second contact 50,51 are contacted with connecting object component 61,
A possibility that being applied to crimping contactor 1A, connecting object component 61 there are the vibration of various frequencies.Therefore, present embodiment
Crimping contactor 1A keeps the spring constant (k1) of the first elastic arm 11 and the spring constant (k2) of the second elastic arm 12 different,
So that the resonant frequency of the first elastic arm 11 and the resonant frequency of the second elastic arm 12 are different.
In the present embodiment, the length of the first elastic arm 11 is made to be greater than the length of the second elastic arm 12.First elastic arm
11 plate is wide wide without biggish difference with the plate of the second elastic arm 12.Make the spring constant (k1) of the first elastic arm 11 as a result,
Less than the spring constant (k2) of the second elastic arm 12, to not make the resonant frequency of the first elastic arm 11 and the second elastic arm 12 mutually not
It is identical.
Therefore, even if the effect of vibration of certain specific frequency is also able to suppress in crimping contactor 1A, connecting object component 61
First elastic arm 11 resonates simultaneously with the second elastic arm 12 and makes the first contact 30 and the second contact 50,51 simultaneously from connecting pair
The case where being left as component 61, it is bad by the conduction caused by vibrating so as to avoid.This makes the company for crimping contactor 1A
It is effective for connecing good aspect.

0.07mm or so (0.04~0.12mm), but it is not limited to the range, according to size, the spring constant etc. of crimping contactor 1A
Specification carries out selection determination.It is formed with the first contact 30 in the end of first part M1, is formed in the end of second part M2
Second contact 50,51 and through hole 52.
As shown in Figure 9, first end 29 is formed and the end of first part M1 is bent to right angle.In addition,
The second end 49 is formed and the end of second part M2 is bent to right angle.
As shown in Figure 10, the first elastic arm 11 is formed and being bent first part M1 helically.
As shown in Figure 11, the second elastic arm 12 is formed and being bent second part M2 helically.Then, lead to
Second elastic arm 12 is bent substantially at right angles and obtained in shown in Figure 12 by the direction as shown in arrow Z3 crossed in Figure 11
Between product 1A '.The back side 49b of the end face 29a of the first end 29 of intermediate products 1A ' and the second end 49 is to be separated from each other
State is opposed.
From, by the direction bearing load shown in arrow Z4, thus making the back side 49b and first of the second end 49 in Figure 12
The end face 29a of end 29 is abutted, and bends the first elastic arm 11 simultaneously with the second elastic arm 12.More specifically, make the first bullet
Property arm 11 and the second elastic arm 12 bend simultaneously in the state that the first elastic arm 11 is in elastic limit the second elastic arm
12 be more than the height of elastic limit.
The permanent deformation for being greater than the first elastic arm 11 is generated in the second elastic arm 12.Therefore, when the load described in the removal,
Two elastic arms 12 can not revert to former height because springback capacity is smaller.Thus, before the height of the second end 49 is than bearing load
It is lower.In contrast, the first elastic arm 11 is intended to revert to former height by rebound.Therefore, as shown in Fig. 2, first end
29 end face 29a is abutted in the state of storing flexible energy with the back side 49b of the second end 49, thus in the first elastic arm 11
Generate initial load.
In this way, the manufacturing method of the crimping contactor 1A of present embodiment includes following process.
(1) the first part M1 with the first contact 30 is formed in the material being made of metal plate and there is the second contact
50,51 second part M2 (Fig. 8)；
(2) first part M1 is bent and forms the first elastic arm 11 (Figure 10) with the first spring constant；
(3) second part M2 is bent and forms second with the second spring constant greater than first spring constant
Elastic arm 12 (Figure 11)；
(4) with the end face 29a of first end 29 and the back side 49b of the second end 49 about the direction of bearing load and it is opposed
Mode configure first end 29 and the second end 49 (Figure 12)；
(5) load of compression is made to be carried on first end 29 and the second end 49 simultaneously, thus make the first elastic arm 11 and
Second elastic arm 12 is bent simultaneously, so that the second elastic arm 12 surpasses in the state that the first elastic arm 11 is in elastic limit
Cross elastic limit；
(6) in the state of unloading in addition to load, the springback capacity of the second elastic arm 12 less than the first elastic arm 11 springback capacity,
It abuts the end face 29a of first end 29 with the back side 49b of the second end 49, and generates the first elastic arm 11 initially
Load (Fig. 2).
It, can be using the spring constant of the first elastic arm 11 less than the second elastic arm 12 by using above-mentioned manufacturing method
Spring constant (11 to the second elastic arm 12 of the first elastic arm is long) condition, by making the first elastic arm 11 and the second elastic arm
12 simultaneously bearing load process to the first elastic arm 11 assign initial load (pretension).
Figure 13 indicates to crimp contactor 1B involved in second embodiment.The crimping contactor 1B is not applying external force
Under free state, the gap of height H2 amount is generated between the end face 29a of first end 29 and the back side 49b of the second end 49.
Therefore, the initial load as the crimping contactor 1A description of first embodiment is not generated in the first elastic arm 11.
Figure 14 indicates the load of the crimping contactor 1B of second embodiment and the relationship of flexure.In connecting object component 61
(shown in Figure 13) abutted with the first contact 30 and load-bearing when the first contact 30, initially only the first elastic arm 11 bend, because
This flexure as increased as being shown L1 as the load increases in Figure 14.
In Figure 14, when load is more than P3, the second contact 50,51 is also connected subject parts 61 and presses, and thus second
Elastic arm 12 is also bent.Therefore, when load is more than P3, be equal to the second elastic arm 12 spring constant (in Figure 14 by void
Load versus deflection characteristic shown in line L2) be superimposed on the first elastic arm 11 spring constant situation, therefore become such as by solid line L3
Such nonlinear load versus deflection characteristic is shown.For structurally and functionally, the crimping of second embodiment contacts in addition to this
Device 1B and first embodiment to crimp contactor 1A general, therefore identical appended drawing reference is marked to the two and is omitted the description.
The crimping contactor 1B of second embodiment also makes first in the same manner as the crimping contactor 1A of first embodiment
The spring constant of elastic arm 11 and the spring constant of the second elastic arm 12 are different.Thereby, it is possible to inhibit the first elastic arm 11
Resonated simultaneously with the second elastic arm 12 based on the vibration of specific frequency and make the first contact 30 and the second contact 50,51 simultaneously from
The case where connecting object component 61 leaves, the conduction caused by can be avoided by vibration are bad.
